FREDERICK HACKMANN, OF'CI-IICAGO, ILLINOIS,

TRACK-ALIGNING JACK.

Application filed January 25, 192%. Serial No. 688,395.

To all whom it may concern:

Be it known that I, Fnnomuon HACK- MANN, a citizen of the United States,and a resident of the city of Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements in aTrack-Aligning Jack; and I hereby declare that the following is a full,clear, and exact description of the same, reference being had to theaccompanying drawings, and to the numerals of reference marked thereon,which form a part of this specification.

This invention relates to a rail aligning jack which is adapted forengaging the lower flange of the rail for shifting the same laterally.

The invention comprises the novel struc ture and combinationshereinafter described and more particularly pointed out and defined inthe appended claims. I

In the accompanying drawings which illustrate a preferred embodiment ofthis invention and in which similar reference numerals refer to similarfeatures in the different views Figure 1 is a sectional view through arailroad track illustrating a pair of my improved rail ali ning jacks,in elevation and in operation.

Figure 2 is an enlarged section through the jack taken substantiallyupon the line.

2-2 of Figure 1, showing parts in elevation.

Figure 3 is an enlarged fragmentary ver tical sectional view with partsin elevation.

Figure 4: is an elevational View of a modified form of the rail engagingelement.

Referring to the drawings which illustrate one embodiment of thisinvention, the reference numeral 1 indicates the base of the jack fromwhich a hollow standard or guide rises. The guide is shown as of hollowrectangular form having an opening 3 (Fig. 2) in its front face. A rackbar l is slidably mounted in the guide 2. The upper end of the rack baris provided with ratchet teeth 5 adapted for engagement'by a pawl (notshown) upon an operating lever 6 pivoted upon thestandard. The operationof such a rack bar by a lever is well known and needs not bespecifically illustrated.

The lower end of the rack bar is provided with a forwardly extending lug7 upon which the rail engaging device is removably are illustrated. Thepreferred form consists of a shoe or supporting member 8 having adownwardly inclined outer end or face 9 and a .mortise or socket in itsinner end which fits the lug 7 as shown in Figure 3. A rail engagingelement lOis pivoted upon the upper outer corner of the shoe 8. The

upper side of this element is serrated forv of rail engaging device. Thesame consists of a rail engaging element having a horizontal portion 11provided with a socket for engaging over the lug '7, and a downwardlyinclined outer portion 12 which extends below the horizontal portion,and

engaging the rail. Y

In use, the jack is positioned adjacent the rail to be shifted oraligned, with the rail engaging element under the rail, as shown inFigure 1. Then by operating the handle 6, the rack bar may be elevatedwhereby the lateral component of force directed against the rail by theinclined face of the rail engaging element will shift the rail laterallyas is apparent.

It will be appreciatedthat the jack is simple in construction andeflicient in operation, the removable feature of the rail engagingelement allows another of greater or less throw to be substituted or anew element substituted if the old one wears out.

I am aware that many changes may be made, and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and I therefore do not purposelimiting the patent granted hereon, otherwise than necessitated by theprior art.

I claim as my invention:

1. In a rail aligning ack, a base, a hollow vertical guide having itsfront side partially open rising from said base, a rack bar slidablymounted in said guide and having a which is serrated upon its uppersurface for.

. supported, Several rail engaging devices lug projecting through theopen side thereof, a support having a downwardly sloping end removablysecured upon said lug, a rail engaging element pivoted to said supportand means for operating said rack bar.

2. In a rail aligning jack, a base, a hollow Vertical guide rising fromsaid base,-a rack bar slidably mounted in said guide and havsupportingmember removably secured upon ing a horizontal lug upon its lower end, a

said supporting member, and means for operating said rack bar.

I 3. In a rail aligning ack, a base, a hollow Vertical guide rising fromsaid base, a rack 5 In testimony whereof I have hereunto sub 20 scribedmy name.

FREDERICK HAOKMANN.
